A seasoned guest speaker will confirm that the corporate world is saturated with office politics and individuals judging one another harshly. Outsiders in the form of invited guest speakers and keynote speakers grab attention and highlight these problems with more credibility than if someone shares the same message within the organization. In addition to addressing the softer skills, guest speakers also emphasize responsibility for one's own personal development as an essential for career progress. A quick word on criticism - constructive and positive criticism is advantageous, but if your colleagues in the workplace start to overpower others with negative comments or gossip, a toxic workplace develops. Mature mindsets acknowledge that everyone has special talents and therefore can strive to a place in the corporate sun. Consider mature guest speakers who have done their time in the field of industry. One of these guest speakers that you can have a look at is Estienne de Beer. His very popular motivational talk "Meerkat Motivation for the Marketplace" is a hit with conference audiences not only in South Africa, but also internationally.
